Human Mastery Over Nature

And, in these cases, somewhat as a pilot, when about losing sight of a coast, whose general trending he well knows, and which he desires shortly to return to again, but at some further point; like as this pilot stands by his compass, and takes the precise bearing of the cape at present visible, in order the more certainly to hit aright the remote, unseen headland, eventually to be visited: so does the fisherman, at his compass, with the whale; for after being chased, and diligently marked, through several hours of daylight, then, when night obscures the fish, the creature’s future wake through the darkness is almost as established to the sagacious mind of the hunter, as the pilot’s coast is to him. So that to this hunter’s wondrous skill, the proverbial evanescence of a thing writ in water, a wake, is to all desired purposes well nigh as reliable as the steadfast land. And as the mighty iron Leviathan of the modern railway is so familiarly known in its every pace, that, with watches in their hands, men time his rate as doctors that of a baby’s pulse; and lightly say of it, the up train or the down train will reach such or such a spot, at such or such an hour; even so, almost, there are occasions when these Nantucketers time that other Leviathan of the deep, according to the observed humor of his speed; and say to themselves, so many hours hence this whale will have gone two hundred miles, will have about reached this or that degree of latitude or longitude.
